Can Hydro Flasks Go In The Dishwasher? The Dos And Don’ts 

Can Hydro Flasks Go In The Dishwasher

Hydro flasks are excellent. They keep your drinks cold or hot for hours on end, and they’re perfect for taking on the go. 

Hydro flasks have quickly become a popular way to keep drinks cold or hot, and many people wonder if they can put them in the dishwasher. 

There’s a lot of debate over whether Hydro flasks are dishwasher-safe or not. And honestly, the answer is a little complicated. 

Some Hydro flasks can go in the dishwasher, while others should not. Here is everything you need to know about Hydro flasks. 

Can Hydro Flasks Go In The Dishwasher?

Yes, but with a few caveats; Hydro flasks made in 2020 and later can go in the dishwasher. Older models are not dishwasher-safe, and therefore you shouldn’t put them in the dishwasher. 

Furthermore, the company clearly states that you shouldn’t put your hydro flask in the dishwasher; doing so will void the warranty. For the best results, we recommend hand washing Hydro flasks with mild dish soap and warm water to preserve the lifespan of your bottle. 

The Hydroflask

Hydro flasks are fantastic pieces of technology. Not only do they keep your drinks cold for hours on end, but they also come in a variety of colors and sizes. The Hydroflask is a vacuum insulated stainless steel water bottle created in 2009. 

Its design allows beverages to be kept cold for up to one day (24 hours) or hot for up to half-day ( 12 hours). 

It has a wide mouth design that allows easy drinking and filling and a powder-coated finish that helps prevent scratches.

The Hydroflask has become popular because it is a high-quality, affordable product. It is the perfect water bottle for active people who like to stay hydrated. 

The Hydroflask is also popular with people who care about the environment because it is made from environmentally- friendly materials. It is made of stainless steel, which means that it is durable and will not leach harmful chemicals into your beverage.

The Don’ts Of The Hydro Flask

You shouldn’t do the following to your Hydroflask, or you could damage the insulation and affect the performance of your bottle:

Put your Hydro Flask in the freezer

Some people like to freeze their Hydro Flasks to keep their drinks cold for a more extended period. Unfortunately, this can do more harm than good. 

When you freeze a Hydro Flask, the water inside expands and can cause the bottle to crack and leak.

If you put a hot drink in a frozen Hydro Flask, the heat will cause the container to shatter. The best way to keep your drinks cold is to store them in the fridge or use an ice pack.

Putting Your Hydroflask On The Stove 

Putting your Hydroflask directly on the stove can damage the insulation and make it less effective at keeping your drinks warm. 

Also, never use a microwave to heat your Hydro Flask. The high heat could cause the bottle to deform or even explode.

Please Don’t Put It In The Dishwasher

Your Hydroflask is a prized possession, and you want to take care of it, so it lasts a long time. That’s why you shouldn’t put it in the dishwasher. 

The high heat and harsh chemicals can damage the coating on your flask and make it less effective at keeping your drinks cold or hot.

Instead, wash your Hydroflask by hand with soap and water. If it’s filthy, you can use a bottle brush to get into all the nooks and crannies. Just make sure to dry it off completely before putting it away.

Soak The Exterior In Hot Water

The team at Hydroflask strongly advises their customers against soaking the exterior of their product in hot water. 

Soaking the surface can cause the paint to peel and flake, and it can also affect the insulation and overall performance of the product.

Instead, Hydroflask recommends that their customers clean the exterior with a soft cloth and warm water. If there is a tough stain or dirt that needs to be removed, you can use a little bit of dish soap.

Use Bleach Or Chlorine To Clean

It would be best never to use bleach or chlorine to clean them. These chemicals can damage the coating on your Hydroflask and cause it to become discolored or even corrode.

The Dos Of The Hydro Flask

Now that you know what you shouldn’t do to your Hydroflask, it’s time to learn what you should do to maintain their long lifespan.

Wash With Bottle Brush

Cleaning your Hydroflask can be a daunting task, but with the right tools, it’s not too bad. The bottle brush is an essential tool for Hydroflask cleaning, and it’s vital to use one specifically designed for cleaning bottles.

The brush should have stiff bristles that can reach all the nooks and crannies of the flask. It’s also essential to use warm water and dish soap when cleaning your Hydroflask. Be sure to rinse it thoroughly afterward to remove all the soap residue.

Here’s how to do it:

  1. Fill your sink with warm, soapy water.
  2. Add the bottle brush and let it soak for a few minutes.
  3. Gently scrub the outside and inside of the bottle with the brush.
  4. Rinse the bottle thoroughly with warm water.
  5. Let it air dry, or you can wipe the outside with a soft cloth.

Use Distilled Vinegar

Distilled vinegar is a great way to clean your hydro flask. It will remove all of the residues from your drink and leave your Hydroflask looking and tasting like new. 

Fill the flask with ½  cup distilled vinegar and close the lid. Shake the flask and let it sit for five minutes. Rinse the flask with water and let it air dry.

Use Baking Soda

Here’s a great way to clean your Hydroflask using nothing but baking soda and water.

  1. Add 2-3 spoonfuls of baking soda to a small amount of water.
  2. Soak your bristle bottle brush in the mixture and use it to scrub on the inside of the water bottle.
  3. Rinse and dry your Hydroflask.

We recommend that you hand-wash your hydro flask with hot, soapy water and a soft brush; this will help ensure that the flask is thoroughly cleaned and lasts longer. Thanks for reading!
